About
Full Stack Software Engineer with 20+ years of experience in architecture and development of web applications, SaaS platforms, and high-traffic e-commerce systems. Based in Salvador, BA, Brazil — available for remote projects worldwide.
Solid experience in enterprise environments with complex business rules: large-scale projects at Grupo Casas Bahia (Via Varejo — Brazil's largest retail group), Infracommerce (Unilever's B2B e-commerce), and mission-critical systems in the travel insurance sector (Coris). Driven by direct business impact with a proven track record of delivery under pressure.
Backend expertise in PHP/Laravel, REST APIs, complex integrations (SOAP, webhooks, ERPs), and modern frontend with Vue 3/Nuxt 3 + TypeScript. Experience with React/Next.js, Inertia.js, and legacy stacks. DevOps with Docker, Kubernetes, GitHub Actions, Linux VPS, and cloud (AWS, Azure, GCP). Technical SEO, Google Tag Manager, GA4/DataLayer, and Adobe Analytics.
At Grupo Casas Bahia, I built a custom Tag Manager that eliminated the need for change management approval — reducing integration publishing from days to minutes. Participated in 3+ Black Friday editions ensuring stability during peak traffic. At Infracommerce, I maintained SOAP integrations with national suppliers for automated B2B order transmission. At DQR Tech, I resolved performance bottlenecks in reports processing 50K+ historical records.
I build my own SaaS products: Trady.chat (trader ecosystem with gamified diary, AI-powered economic calendar, and real-time B3 quotes via WebSockets), DopaCheck (habit tracking with social accountability and WhatsApp check-in), Rateio Justo (AI-first bill splitting, serverless on Vercel with PIX payments), and mkit.com.br (micro bio sites for creators with Instagram Graph API).
As a freelancer, I've delivered high-impact automation projects: FIES enrollment automation for FTC University via web scraping (eliminating 100% manual process), FGTS individualization for Brazilian municipalities (integration with Caixa Econômica Federal's REMAG/SEFIP systems), corporate websites for Shopping Iguatemi Salvador, and the GlobalCard student ID card system.
In the financial market, I've built MQL5 bots for MetaTrader 5 and real-time Forex/B3 data ingestion features. Intermediate/technical English — advanced reading and writing, intermediate conversation.
